A Jaz drive, also called a Jaz disk, is a removable hard disk drive manufactured by Iomega. According to PCMag.com, the Jaz drive was introduced to the market in late 1995.
The original Jaz disk drive was a 1GB removable disk cartridge. The updated version, introduced in 1997, had a 2GB capacity.
Following its introduction in 1995, the Jaz drive was popular among users in this niche, and Iomega introduced the higher capacity 2GB drives in 1997. In 2003, Iomega discontinued the manufacture of new Jaz drives, but it continued to provide customer support for existing owners. Jaz was followed in 2004 by the REVolutionary disk, or REV drive, which had a capacity of 35GB.
